Very nice, but fails with public keys

Hi,
libssh2_userauth_publickey_fromfile (sess, user, psrv_key.pub, psrv_key.priv, 0) and or
ibssh2_userauth_publickey_fromfile_ex and or
ibssh2_userauth_publickey_frommemory all fails
with -18. while the at the shell the: ssh -i ./psrv_key.priv user@server works fine.

@marriusco ibssh2_userauth_publickey_frommemory only works if you use OpenSSL as backend so I think this issue can be closed.

For any future users, we only need to add a negation in this if condition:

if (libssh2_userauth_publickey_fromfile(session, username, keyfile1,
                                           keyfile2, password)) {
         fprintf(stderr, "\tAuthentication by public key failed!\n");
         goto shutdown;
}
